Problems solved by technology
However, for spliced display panels, since the sub-board and the motherboard are connected together by pads, for sub-motherboard-style spliced display panels, due to the innovative splicing process, there is a gap between any two adjacent sub-boards , so that the four sides of the sub-board are exposed to the air, and the edges of the functional optical film on the sub-board are also exposed to the air for a long time
The splicing display panel is easily affected by high temperature and high humidity and other environments during long-term use, resulting in the intrusion of water and oxygen, resulting in failure of sub-boards and functional membranes, resulting in abnormalities in the entire splicing display panel, and failure of the final product
Therefore, the traditional packaging process cannot meet the reliability requirements of spliced display panels

Abstract
The invention discloses a tiled display panel. The tiled display panel comprises a first substrate, at least two second substrates and a packaging body. The two second substrates are arranged on the first substrate at intervals. And a gap is formed between the two second substrates. The second substrate comprises a light-emitting functional layer and an optical structure layer arranged on the second substrate. The packaging body covers the surfaces, away from the first substrate, of the at least two optical structure layers and fills the gap. According to the splicing display panel, the packaging bodies are arranged on the second substrates, the packaging bodies are attached to the faces, away from the first substrate, of the second substrates, and the gaps are filled with the packaging bodies, so that the at least two second substrates are completely packaged, and the situation that a light-emitting function layer of the splicing display panel is eroded by water and oxygen, and consequently the splicing display panel fails is prevented.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a mosaic display panel. Background technique [0002] The current organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel mainly uses the ink-jet printing (Ink-Jet Printing, IJP) process to form organic and inorganic encapsulation layers inside the panel to block water and oxygen, thereby protecting the panel from Water oxygen damage. However, for the spliced display panel, since the daughter board and the mother board are connected by pads, for the daughter board type spliced display panel, due to the innovative splicing process, there is a gap between any two adjacent daughter boards. , causing the four sides of the daughter board to be exposed to the air, and at the same time, the edges of the functional optical film on the daughter board are also exposed to the air for a long time. When used for a long time, the splicing display p...
